Being infected by virus or malware is something very common these days. Sometimes it’s very hard to remove these infections. Modern forms of malware try to avoid detection by altering the Operating System. Others attack your antivirus so it cannot work properly. This means that if you get infected by a virus newer than your antivirus definitions there is a chance you can’t get rid of it.

In this post I am going to address this problem and show you a way to solve it.

Safe Mode and How Important is to Control Viruses

As I have explained before a virus tries to hide its activity by changing the default Operating System’s behaviour. To do that it usually load programs at Windows Start Up. A way to stop this is using the Safe Mode. In Safe Mode, Windows only loads the essential services making it harder for the antivirus to work.

The way I prefer to enter Safe Mode is using MsConfig. Of course you can use F8 at boot but sometimes you miss your chance (or can’t be sure when) to press that key when Windows is loading.

Safe Mode In Windows XP

Press WinKey + R, type msconfig and press Enter.

Go to Boot.ini tab and select /SAFEBOOT and MINIMAL. This way the minimum number of files will be load in the next reboot. Once you enter on Safe Mode you have to change this so Windows start in normal mode.

Next time you boot you will see something like this:

Safe Mode In Windows Vista and Windows 7

As we have done before with Windows XP, press WinKey + R , type msconfig and press Enter.

Go to Boot tab, select Safe boot and minimal, don’t forget to press Set as default. As you can see is very similar as we have done on Windows XP.

Here you can see a Windows 7 in Safe Mode.

Portable Antivirus Software – Why it’s so Important

I have written how common it is that viruses change antivirus software so these programs can be rendered useless. You cannot always rely on your installed antivirus if you have an infection. So you need a program that don’t need to install. You cannot install anything while in Safe Mode; however, most antivirus software have a portable version. These portable versions don’t need to change anything in your machine so they can work in Safe Mode.

The best way to download the following software is on another machine that is not infected. Once you have it you only need to double click to execute. Usually they will need to update before you use, so do it before entering in Safe Mode (on the other machine on which you downloaded it.)

What are the next steps after win key + r, then putting safe boot and minimal and set as default is not highlighted. I clicked apply, it restarted and brought me back to safe mode so what are the next steps to delete all viruses. I put safe mode & networking to access Internet to download anti virus but Mozilla fire fox nor windows explorer is not connecting to Internet or not loading up. Windows 7 (64 bit)
